Local DNS Records
N
where
N
= 1 – 32
One of 32
Local DNS Records
(numbered 1 – 32). Each
record is a mini script of the following format:
Name
=
A
,
A
,
A
,...
or
Name
=
R
,
R
,
R
,...
where
Name
represents the domain name to be resolved
locally, and has the format
domain
(such as
machine.sip+obihai.com
). Everything after ‘
+
’ is
considered as the domain to be appended to the host field in
each
R
on the right hand side. ‘
+
’ is optional; if missing, the
full domain must be used in every
R
.
A
represents an
A
record that is just an IP address, such as
192.168.12.17
.
R
represents an SRV record and has the format:
{host:port,pri,wt}
where
•
host
is a host name with or without domain part (such as
xyz, xyz.abc.com.
). A dot (.) at the end of host
indicates it is a complete host name that does not require
the domain to be appended.
•
port
is a port number (such as
5060
)
•
pri
is the priority. Valid value is
0
(
highest) –
65535
(lowest)
•
wt
is the weight. Valid value is
0
(
lowest) –
65535
(highest).
wt
is optional. If not specified, the default is
1
.
•
pri
is optional only if
wt
is not specified.
1
is the default if
not specified.
•
port
is optional. The default to use is based on the
protocol (
5060
for SIP,
80
for HTTP, and so forth).
The enclosing curly braces
{ }
are also optional if there is
only one
R
; or if there is no comma used inside the
R
.
Examples:
•
_sip._udp+obihai.com=abc,xyz,pqr:5080,{mmm,2
},{super.abc.com.}
•
abc.obihai.com=192.168.15.118,192.168.15.108
If the
A
record of a given host name can’t be found in any of
the
Local DNS Records
, the device attempts to resolve it
using external DNS queries.
Any change applied to
Local DNS Record
needs a reboot in
order to take effect.
